Axially phase-matched parametric six-wave mixing was achieved in Rb and the parametric six-wave mixing signals in the infrared range were detected.Tunable signals in the visible range were produced by sum-frequency mixing of the pump laser and the parametric six-wave mixing signals in the infrared range.And,quantum beating at a frequency of 608 cm-1 was observed from the sum-frequency signal,indicating that the coherent properties of atoms and molecules can be studied by means of quantum beating recovered from parametric six-wave mixing signals.Axially phase-matched parametric six-wave mixing was achieved in Rb and the parametric six-wave mixing signals in the infrared range were detected.Tunable signals in the visible range were produced by sum-frequency mixing of the pump laser and the parametric six-wave mixing signals in the infrared range.And,quantum beating at a frequency of 608 cm-1 was observed from the sum-frequency signal,indicating that the coherent properties of atoms and molecules can be studied by means of quantum beating recovered from parametric six-wave mixing signals.

Observation of Quantum Beating from Two Coupled Parametric Six-Wave Mixing Signals in Rb

Zhu Chang-jun, Junfang He, Zhai Xue-jun +1 more

Two processes of coupled difference-frequency axially phase-matched parametric six-wave mixing are carried out in Rb vapour by two-photon excitation using fs laser pulses, and parametric six-wave mixing signals in the infrared and near infrared regime are detected. The infrared parametric six-wave mixing signals are up-converted into the visible spectral range by sum-frequency mixing with the pump laser in a LHO 3 crystal. Moreover, quantum beating at 608 cm -1 , corresponding to the 7 s – 5d energy difference in Rb, is observed from the sum-frequency signal at 495 nm. As a result, we obtain modulated light signals in the visible, near infrared and infrared spectral ranges, and study the interference between 7s and 5d states of Rb.Two processes of coupled difference-frequency axially phase-matched parametric six-wave mixing are carried out in Rb vapour by two-photon excitation using fs laser pulses, and parametric six-wave mixing signals in the infrared and near infrared regime are detected.

Axially phase-matched parametric six-wave mixing (PSWM) has been observed in Rb vapor by two-photon excitation of the atom $(5s\ensuremath{\rightarrow}\ensuremath{\rightarrow}7s,5d)$ with $\ensuremath{\sim}150\phantom{\rule{0.3em}{0ex}}\mathrm{fs}$ pulses, centered at $\ensuremath{\lambda}\ensuremath{\sim}769\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ and generated by a $\mathrm{Ti}:{\mathrm{Al}}_{2}{\mathrm{O}}_{3}$ laser system.
